Factorial validation of malaysian adapted brunel mood scale in an adolescent sample

Purpose: The present study investigated the psychometric properties of a Malaysian adapted Brunel Mood Scale.

Methods: The questionnaire was administered to 355 young sport athletes with a mean age of 14.69+1.70 years. Confirmatory factor analysis (CFA) and Cronbach's alpha were used to determine the factorial validity and the internal consistency of the questionnaire respectively.

Results: CFA results revealed adequate model fit, best represented by a 6-factor model with one of the items removed (item 24). Internal consistency of the questionnaire was marginally supported through alpha reliability method. Alpha coefficients of 0.72, 0.64, 0.73, 0.69, 0.65, and 0.58 were obtained for tension, depression, anger, vigour, fatigue and confusion subscales respectively. Closer inspection of items for confusion revealed a 'problematic' item (item 24/uncertain). Removing this item increased the alpha coefficient to 0.67 for this subscale.

Conclusion: It was concluded that this questionnaire may be used to measure differentiated negative and positive mood states among Malaysian adolescent athletes. However, further analyses involving independent samples are needed to confirm the present findings.
